Join a network of premier experts in Androgen Excess Disorders.

The Androgen Excess and Polycystic Ovary Syndrome Society
is an international organization dedicated to promoting the
generation and dissemination of knowledge related to
all aspects of Androgen Excess Disorders.

PCOS is the most common androgen-excess disorder, and affects between 5% and 10% of all women.
PCOS typically involves the prescence of irregular or absent menstrual periods in combination
with excess androgens (male hormones) and
possilby polycystic ovaries. Increased production or sensitivity to androgens commonly leads to hirsutism
(male-patterned hair growth), acne, or alopecia (thinning or loss of scalp hair).

Congenital adrenal hyperplasia, also known as CAH, is an inherited disorder affecting
the hormones produced and released by the adrenal glands. Approximately 1 in 12,000 infants is affected by CAH.
The most common type of CAH is called 21-hydroxylase deficiency which is due to
changes in the gene (DNA) that codes for the protein, 21-hydroxylase (CYP21A2).

Premature pubarche is the untimely development of pubic hair and/or axillary (armpit) hair prior to 8 years of age in girls and prior to 9 years of age in boys.
The most common cause of premature pubarche is early maturation of the adrenal glands (adrenarche)
which results in earlier than normal production and release of androgens, such as dehydroepiandrosterone
sulfate (DHEAS).
